    • An automatic transmission comprises a metal V-belt mechanism 10, which changes the speed ratio of the rotational output from an engine ENG, a forward/reverse direction change mechanism 20, which switches the rotational direction of the ratio-change mechanism, and a forward clutch 30, which actuates the switching operation of the rotational direction performed by the forward/reverse direction-change mechanism. A control system for this transmission comprises a regulator valve 50, which generates a line pressure, a manual valve 80, which is operated in correspondence to the shift lever and switches the supply of the line pressure to the forward clutch, and a drive-range sensor 105, which detects the operation of the manual valve. When the movement of the manual valve to a position where the line pressure is to be supplied to the forward clutch is detected by the drive-range sensor 105, the line pressure, which is adjusted by the regulator valve, is lowered for a predetermined time period.
    • 一种自动变速器包括:金属V型皮带机构10,其改变来自发动机ENG的旋转输出的速度比,改变比例变化机构的旋转方向的前进/后退方向改变机构20; 离合器30,其驱动由前进/后退方向改变机构执行的旋转方向的切换操作。 用于该变速器的控制系统包括产生管路压力的调节阀50,对应于变速杆操作并将管路压力的供给切换到前进离合器的手动阀80以及驱动范围 传感器105,其检测手动阀的操作。 当通过驱动范围传感器105检测到手动阀的运动到向前方离合器供给的位置的位置时,由调节阀调节的管路压力下降预定时间 期。
